[PATCH] input: surface3_spi: make const array header static, reduces object code size

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Don't populate the const array header on the stack, instead make it
static.  Makes the object code smaller by over 180 bytes:

Before:
   text    data     bss     dec     hex filename
   6003    1536       0    7539    1d73 surface3_spi.o

After:
   text    data     bss     dec     hex filename
   5726    1632       0    7358    1cbe surface3_spi.o
